SWABIAN INSTRUMENTS is a pri­vate owned busi­ness in Ger­many that devel­ops and man­u­fac­tures soft­ware and hard­ware for data acqui­si­tion and instru­ment con­trol. Swabi­an designs and man­u­fac­tures data acqui­si­tion and sig­nal gen­er­a­tion sys­tems for research and indus­try. Our sys­tems are easy to use and packed with use­ful fea­tures. This is achieved by shift­ing some of the hard­est tasks from the hard­ware to the soft­ware lev­el. This makes the sys­tems flex­i­ble and extend­able, which is called “Soft­ware Defined Data Acqui­si­tion”. Swabian’s sys­tems cov­er a fre­quen­cy range from DC to 50 GSa/s. Swabi­an Instrument’s com­mer­cial prod­uct “Time Tag­ger 20” is emerg­ing as one of the most pow­er­ful data acqui­si­tion tools used by the physics research com­mu­ni­ty from quan­tum optics to bio physics.
